Using Multiple Antennas At A Station Patents (Class 370/334)
  • Patent number: 10594445
    Abstract: A method and system to improve the link budget of a wireless system using fast Hybrid Automatic Repeat Request (HARQ) protocol. In one embodiment of the invention, the Medium Access Control (MAC) logic in a base station determines whether the quality of the communication link with a mobile station is bad. When the MAC logic in the base station determines that the quality is bad, the base station uses a fast Hybrid Automatic Repeat Request (HARQ) protocol to indicate to the mobile station to send identical information to the base station in each of a plurality of successive or consecutive communication intervals before processing any received identical information from the mobile station. The fast HARQ protocol reduces the latency of receiving the identical information correctly, as compared with the current HARQ protocol.

  • Patent number: 10531412
    Abstract: Wireless communication is performed by stations (nodes) in a wireless mesh network by forming nodes into a mesh network without the need of network-wide synchronization and without needing to form active links between potential neighbors. Nodes obtain information on neighbors in the network by listening to transmitted beacons from these nearby nodes. Synchronization and active links are established when a data transmission session is triggered and initiated by the route setup process. The link formation process performed when establishing a new route performs both beamforming and synchronization. In situations in which a new route does not intersect other active routes then independent synchronization is performed; but when intersecting routes exist, the new route is synchronized with all intersecting routes where nodes are configured to serve both routes.

  • Patent number: 10178124
    Abstract: Channel based authentication schemes for intrusion detection that operates at the physical layer are described that apply the capabilities of a pattern reconfigurable antenna for improved performance. Performance gains are achieved by the schemes as a function of the number of antenna modes. The first scheme relies on a channel based fingerprint for differentiating between transmitters whereas another scheme poses the intruder detection problem as a generalized likelihood ratio (GLR) test problem that operates on the channel realizations corresponding to different modes present in a reconfigurable antenna. The benefits of these two schemes over single element antennas are demonstrated. General guidelines are provided on how to choose the different elements of the decision metric in order to realize better performance for physical layer based authentication schemes based on any diversity scheme.
